Taigate - door locks - fusible link question

[mgmann]

Recently had some work done on my 88GW. When I got it back the rear window wouldn't work using the key and the door locks don't work. The rear window works from the dash.


I know that those 2 items are on the same circuit and are controlled by a 30 amp breaker. I checked the breaker using an ohm meter and it seems fine.


Some posts have mentioned a fusible link that comes before the breaker. Where is that link located and how can I identify it?


Thanks..........

I would look to the driver panel switches and door lock actuators for corrosion and the tailgate key switch in the tailgate for corrosion.

What did they do?

Had the rig painted, new vinyl, etc. I couldn't get the rail off of the tailgate window so bought a new rail and took it to a glass place to have it installed along with a new windshield. It was all working fine when I took it to them. I get the feeling that they shorted something out when they put in the tailgate window. I had replaced the tailgate key switch a few years ago and made sure nothing was shorting out inside the tailgate, so who know what they did to mess it up.

I'm not getting any voltage reading at the breaker which is why I'm thinking that a fusible link may have gone out although that doesn't make much sense either since the breaker seems ok.

Guess I'll take the window out and see what I can find. What a pain in the butt.

I would say its good if your getting power to it from the front switch.Id ask the installer to fix it if they caused it if possible.

I wouldnt think its a fused link.

If your good enough to take apart the switches at the door and the front switch, and clean them I bet things will work better. Take them apart inside a box or something so you don’t lose any small parts or springs.

Check the passenger side door lock switch to see if it works. Might provide a clue.

GL!

1st. does tailgate motor work 2nd. look between tailgate and body, make sure tailgate wire harness isn't pinched or broken wires fro tailgate harness 3rd. motor plugged up, something isn't plugged up

The '88 diagram shows 4 fusible links: http://oljeep.com/gw/elec/88/88_FSJ_WiringDiagramPage1.jpg

They are all right at the starter solenoid.

I would find the tailgate relay on these sheets http://oljeep.com/gw/elec/GW_wiring.html and follow it backwards to see if it's powered by one of the fusible links. Likely. Fusible links go open when shorted, and the insulation sometimes stays in place. Test for continuity with your multimeter.
